Hydroxypropyl Methyl Cellulose (HPMC) introduction:

  Hydroxypropyl methyl cellulose (HPMC) is a type of non ionic cellulose ether made from natural high molecular materials through a series of chemical processes.With almost all properties of methyl cellulose(MC),it is the auxiliary agent of first choice in the production of top-quality construction materials. To satisfy the requirement of environment protection, Zhicheng brand product is developed and produced particularly tor the construction material industry, with such favorable features as high water retention, good dispersibility, high degree of fineness, nice place ability and convenience to dissolve, it is applicable to the production ofinnovative construction materials like dry-powder mortar, waterproof putty powder(paste) for indoor and outdoor walls binding agent, joint filler ;interface finishing agent,water paint, self-leveling agent,etc. In the production of construction materials, cellulose ether is an indispensable additive.

Physical and chemical properties：

1.Appearance: HPMC is White or off-white powder.

2. Dissolvability: HPMC is dissolvable in cold water and clear or slightly cloudy liquid cement, but almost insoluble in ethanol, ether or acetone. In addition, HPMC is soluble in some organic solvents or some mixed solvents of water and organic solvents.

3. Granularity: Throughput rate:≥99.5% for 100 mesh and up to 100% for 80 mesh.

4. Apparent Density:0.30-0.70 g/cm³ and density:1.26-1.31 g/cm³.

Application Manual： 

Product features:

1. Salt resistance :HPMC is a non-ionic cellulose ether, not a polyelectrolyte. Therefore, it is relatively stable in water in the presence of metal salts or organic electrolytes. But too much electrolyte can lead to gelatinization and precipitation.

2. Surface Activity: HPMC water solution has surface activity, which enables it to act as colloidal protective agent emulsifying agent and dispersant agent.

3. Thermal Gelatinization: HPMC water solution will turn to opaque gel and settle when heated to certain temperature, but will restore to the original solution when it is cooled down continually . The temperature leading to such gelatinization and sedimentation depends mainly on the types, concentration and heating rate of HPMC water solution.

4. PH Stability: The viscosity of HPMC water solution is hardly affected by acid or alkali, and it is relatively stable when pH value is in the range of 3.0 to 11.0.

5. Water retention: HPMC is a type of high-efficiency water retention agent that is widely used in the production of ceramics construction materials and many other fields.

6. Adhesivity: HPMC, as a type of high-performance binding agent ,is applicable to the production of coloring pigments tobacco products,ceramic products and paper making.

7. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.8.Slip Resistance: lt can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
